On the highway of life, are you the bug or the windshield?. Bug hits windshield. The force on each is…. The same- Newton’s third law - You can only exert back as much force is exerted on you. The time of impact is….
E N D
The force on each is… The same- Newton’s third law - You can only exert back as much force is exerted on you
The time of impact is… The same- It would be impossible for the bug to hit the windshield for 2 seconds while the windshield hits the bug for 3 seconds
The change of velocity on each is… Very Different – Newton’s First Law -The car, hardly noticeable. The bug very noticeable. The bug slows down, stops and reverses direction
The momentum before and after… The same – Newton’s Second law momentum is conserved in a collision
The force on each is… The same- Newton’s third law - You can only exert back as much force is exerted on you
The time of impact is… The same- It would be impossible for the bug to hit the windshield for 2 seconds while the windshield hits the bug for 3 seconds
The change of velocity on each is… Slightly Different – Newton’s First Law- The car, slows down noticeably, The bug slows down stops and reverses direction
Its only a Small force when a bug hits the windshield It only takes a small force to kill a bug. That same size force won’t hurt the windshield
The difference, the size of the force and momentum, the smaller bug has less force and change in momentum, the bigger bug has more force and change in momentum.
